We look at the division of 673920 by 56 
The aim is to understand the frequency of 56 in 673920.

Going ahead to step 1:
56 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 56

Going ahead to step 2:
56 can be fit into 67 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 56 from 67 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 56

Moving on to step 3:
If we divide 113 by 56, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 112 from 113, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 56

Moving on to step 4:
19 divided by 56 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 56

Moving on to step 5:
The number 56 fits into 192 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 1203.0
Subtracting 168 from 192 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 56

Advancing to step 6:
The number 56 fits into 240 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 12034.0
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
When dividing 160 by 56, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 12034.2
Subtract 112 from 160 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
If we divide 480 by 56, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 12034.28
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 56, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 12034.285
Subtracting 280 from 320 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 56, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 12034.2857
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 56 is 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 12034.28571
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
56 goes into 240 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 12034.285714
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
160 divided by 56 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 12034.2857142
If we subtract 112 from 160, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
56 can be fit into 480 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 12034.28571428
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 12034.28571428 with a remainder of 3.2e-08.
